ASSIGNOR TOA 'IE-HE DENT HARDWARE COMPANY, OF FULLERTON, PENNSYLVANIA, CORPORATION OF ENN- Y sYLvANrA REVERSIBLE s'ror FASTENER Original application Vfiled July 11,"1927, Serial No. 204,832.` Dividedv and this application filed January f ,l l. 4, 1929. Serial No. 330,323.

This invention relates to a` reversible' closure fastener of the type that is'especially designed for use on hinged refrigerator-doors or similar closures.

VMore particularly, Vthis invention relates to a fastener that includes a bolt so mounted that it-may be moved in either direction from a central orv operative position so that 'the fastener may be appliedto 'a door, that is hinged at its left side, or to a door that is hinged at its ri ght' side, without any change whatever being required in the fastener in orderyto adapt `it to a door which it is to be appligd. f

It-has heretofore been proposed to provide such fasteners with a plurality of stops, each serving to maintain the bolt-'in one of its inoperative positions. By this invention an improved fastener of this kind is 4presented in which an improvedI` stop arrangement of extreme simplicit-y in construction, and that may beoperated with certainty is provided.

primary object of the invention is to provide a fastener of the type just described, in which the bolt swings about a fixed pivot so that each part thereof moves Ain a sub? stantially arcuate path and in which depressions are provided in vthe bolt Vcasing to re# ceive projections from the bolt, which depresions are located concentrically with respect to the invariable bolt pivot so that they will receive the projection of the bolt with certainty when thebolt is moved toeither of its vinoperative positions.

A further obj ect of the invention is to provide a reversible fastener of the stop type, that is inexpensive to construct and embodies few simple parts that are so formed and assembled that a fastener having a long life is provided. f

Further objects ofthe invention will appear as a description thereof proceeds with reference to the accompanying drawings, in

which:

Like reference characters indicate like parts throughout the several views.

In the drawings, the numeral 10 indicates av housing for the fastener. Said housing' is provided with lateral projections 11 that are perforated as shown at 12 in order that fasteners may be applied to secure the housing to the closure or door. The edges of the latplane indicated bythe line 5 5 eral projections 11 are turned inwardly to provide flanges, as shown `at 13, to space the housing and said projections from the' face of the closure to which the fastener is applied,

and so as to space the housing from the face serves as a pivot for a bolt lthat is provided with a tapered opening 16 designed to receive said. post when the bolt is assembled in the housing. `The* smaller dimension of the tapered opening 16 corresponds approximately to the diameter of the post 111 so that the boit is guided in a substantially arcuate path with respect to said post as an axis. The opening 16 is tapered so that the bolt may be tilt-ed toward and from the top of the housing l() and toward and from a cover plate previously referred to. It will be observed that in view of the fact that the smaller dimension of the tapered opening 16 corresponds approximately with the diameter of the post 14 that such lateral tilting of the bolt can take place while the bolt is moving in a definite arcuate path.

The bolt 15 is provided with an end 17 projecting from the housing and designed to engage a keeper to be later described. The bolt 15 is also provided with a handle 18, of any suitable form, and by which the bolt is manipulated. Adjacent the opening 16 in the bolt 15, the bolt is provided with a pair of lateral projections or arms 19 and 20, each ot which is provided with a. finger 21 extending rearwardly of the front tacel of the housing 10 when the bolt is assembled in said housing. At a point spaced substantially endwise of the bolt 'troni the opening 16, it is provided with a shouldered lug 22 provided to cooperate with the walls ot depressions about to be described, to hold the bolt in either oit its inoperative positions.

,il coil spring 23 is coiled around the post 1+ibetween its ends and the ends 2-'1- and 25 thereof' extend radially Tfrom the post l-Il and in substantial alinement, so that said ends bear against the fingers and 21 ec `ively, carried by the bolt 15. The housing 1() is provided with inwardly extending projections 26 and 27, against which the ends 2l and of the spring 23 rest when the bolt is in its operative position, as shown in 1. The coil spring 23 is so arranged that the arms 2st and 25 thereof engage the stops 2G and 2T firmly under tension, when the bolt is in its operative position so that said s )ring tends to hold the bolt in its inoperative position.

A cover plate 2S, provided with recesses 29 to permit the cover plate to iit around the edges ot the fianges 13 ot the lateral eXtensions 11 oi" the bolt housing, in order that said cover plate may be non-rotatively positioned with respect to said housing, closes the rear of said housing. Said cover plate is secured to the housing, preferably, by a screw 30 engaging a threaded bore 31 in the post 1st. The cover plate is provided with a plurality ot depressions preferably formed by stamping slots and 33 in said cover plate. Said slots are arranged with their centers on the arc ot a circle drawn from the center ot the post 14 about which the bolt 15 moves in order that they will be in position to receive the lug ot the boit 15 when it is moved to either of its extreme positions.

For cooperation with the Jfastener just described, a keeper or the type illustrated in Fig. 6 is preferably employed. Said keeper includes an attaching portion 34s and an outwardly extending portion 'formed to provide a shoulder 3G with which the end 17 ot the bolt 15 engages when said bolt is in its operative posi ion. ri`he projection 35 is provided with an inclined bolt guiding surface 3T provided to retract the belt when the door is closed ii, 'for any reason, it is not held in its retracted position by the stops. Above the projection 35 the keeper 34 is provided with a trip iinger 38 for a purpose presently to be described.

In the operation of the fastener of this invention, when the bolt 15 is in its operative position shown in Fig. 1 of the drawings, it is in engagement with the shoulder 36 ot the keeper which keeper is attached to the frame of the door adjacent the door in well known manner. `When it is desired to open the door the handle 18 is grasped and the bolt is swung on the pivot atthe same time. At the same time that the bolt is swung on its pivot a pull is exerted on the handle to swing the door on its hinges. Such pull assists to tilt the bolt with respect to the post 14, causing the lug 22 to enter one ot the depressions or openings 32 or 33 in the cover plate 28 when said lug is brought into registry therewith. lnasinuch as the path ot' movement of the bolt is deiinitely predetermined by the act that it is pivoted on the post 14, the lues 22 may be readily entered in either of said openings. YFurthermore, as said openings may be formed by simply stamping them in the cover plate during the course of its manutacture, it will be understood that the provision ot the depressions or openings to receive the lug on the bolt is a matter of extreme simplicity and entails substantially no added cost to the production of the fastener. 1t will be observed further, that the openings stamped trom the cover plate provide square shoulders that, when engaged with similar shoulders provided on the lug 22, serve to iirmly hold the bolt in its retracted position. It will be noted that the cover plate is tree of projections on its inner surface that might intertere with the tree movement ot the bolt.

l lt will be understood that the operation of the fastener is precisely the same when it is applied to a door hinged at its right hand side, as when it is applied to a door hinged at its lett hand side, though when the tastener is used on one of the types of hinged doors, just referred to, the lug 22 on the bolt engages the opening 32 in its retracted position and when it is used on the other type of door said lug engages the opening 33 of the cover plate.

This application is a division of my copending application, Ser. No. 204,832, tiled July 11, 1927.

The invention may be embodied in other specific forms without departing from-the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency oi the claims are theretore intended to be embraced therein.
